Assume a app generates a message (stack on computer).Each layer of the sending entity will put then control information in the data depending on the protocol and transmit the data to the next lowe...
Assume we have a channel and send 7-bit data(0100100) asynchronously with 1 parity bit(0).Suppose the start bit is 1.The end bits are in the same logic level with the idle state of the channel(0).H...
In this datasheet it says that the minimum resolution is 0.1uA for the 10mA range.What is this minimum resolution?Is it the sensitivity of the multimeter for the 10mA range?
Can we find the internal resistance of a multimeter ,when we use the multimeter like a ampmeter, from its datasheet? I am trying to find the internal resistance of IDM 505 and I went to the datash...
Assuming we have a voltage regulator : Why do we have to ground Vin and Vout using 2 capacitors just like that?Co could be to provide a low resistance path to GND at high frequencies but what is...
A while ago I made a question about the monostable multivibrator .Lets get a picture of it: When switch is closed it enters its unstable state and it eventually returns to the stable state Howe...
I have this circuit: I think that R3 acts like a feedback path from the output to the input.However I am not sure what will happen if I change the value from 100Ohms to lets say 1kOhms. I have ...
I have learnt that if we have 2 parallel conductive plates and we seperate them the capacitance is increased if we put a good conductor between the plates. Now the resonant frequency of a inductor...
In monostable multivibrators we use a trigger signal applied to the base of the transistor which is usually off to enter the astable region Can we instead have a pin which is connected directly ...
Which capacitors have smaller self resonance frequency?I would bet my money on electrolytic capacitors because they are usually much bigger than the ceramic capacitors however I don't know if they...
What is a typical value for capacitance of a real inductor? Does this internal capacitance exist only under AC and not DC?
It all depends on the values of the components:If the system will very slowly decay until the energy of the system reaches 0. If the system undergoes something which will look like a part of...
How to find the equation of voltage of the top common node of R1,L1 and C1 after the switch is moved?
Suppose we have a sine signal applied to a inductive load. Is the inductance of the load changed if the frequency of the signal is changed?
It all depends on the values of the components:If the system will very slowly decay until the energy of the system reaches 0. If the system undergoes something which will look like a part of...
How to find the equation of current of the RLC circuit after the switch is moved?
When 2 inductors share the same magnetic field they become coupled and besides their self inductance they have a mutual inductance as well. For this circuit: Now current entering one coil marke...
Which will be the total series inductance?
After the switch is closed: The general formula for finding the voltage of the capacitor is: where Vf is the voltage of the inductor after infinite time,Vo is the voltage of the capacitor at ...
How do I find the voltage of the capacitor and the current through the capacitor after the switch is closed?
After the switch is closed : The general formula for finding the current through the inductor is this: where If is the current through the inductor after infinite time,Io is the current of th...
How do I find the current through the inductor and the voltage of the inductor after the switch is closed?
A diode obeys the Shockley diode equation and for this circuit we have: The current through the diode must not pass a limit so for LTL-307EE we go to the datasheet to find the maximum current be...
Suppose we have this circuit How do I pick a appropriate value for the resistor R1?
Based on this paper on Wiki a diode can be described as a frequency mixer due to the exponential relationship between current and voltage.What I don't get from which point to which point do we meas...
